🔌 Function

The heat exchanger transfers engine or generator coolant heat into the raw-water circuit while keeping the two fluids separated. This maintains the correct closed-circuit operating temperature and protects the engine from direct seawater circulation.

Common signs of failure:

• Engine or generator overheating under sustained load

• Coolant loss without an obvious external hose leak

• Saltwater and coolant cross-contamination

• Restricted raw-water discharge or uneven end-cap temperature

• Corrosion, green staining, cracked solder joints or pressure-test failure

📦 Condition

• New aftermarket replacement part

• Brand new

• Supplied in original or equivalent packaging
